Evaluation of the Coulter Counter S-Plus VI

Evaluation of an automated instrument for viability and concentration measurements of cryopreserved hematopoietic cells.

Two important parameters for determination of deleterious effects of cellular processing on hematopoietic progenitor cells are cell viability and concentration. The Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins Hospital evaluated the Beckman Coulter Vi-Cell automated instrument for the measurement of these two parameters. Using 33 thawed hematopoietic progenitor cell samples, autom...

An evaluation of the Coulter S counter.

Estimation of lymphocyte percentage and number on the Coulter Counter, Model S Plus Phase II.

The Coulter Counter Model S Plus Phase II provided precise measurements of lymphocyte percentage and count and carry-over was negligible. Lymphocyte percentage values agreed well with those from the stained blood film except when the percentage was high and in these circumstances the instrument gave underestimates. When making artificial mixtures with increasing lymphocyte count a progressive u...

The Construction of a Micro-coulter Counter Device

This report explains the general applications of the Coulter counter, discusses its benefits, and reviews literature in which researchers have used the device as a research tool and in biosensor applications. Coulter counters are electrofluidic devices commonly used to measure the size and the number of particles in a sample. The paper also reports the design and fabrication of a Coulter counte...

Detection of important abnormalities of the differential count using the Coulter STKR blood counter D F BARNARD , S A BARNARD

An assessment of the three part differential provided by the Coulter STKR blood counter showed good correlation when compared with an 800 cell manual differential. Satisfactory flagging of eosinophilia, basophilia, and the presence ofimmature cells was found. The use of variables derived from the STKR in conjunction with interpretive reporting and user-defined flagging enabled this department t...
